The group has also been involved in the development of nucleophilic fluorination chemistry allowing the creation of pharmaceutically relevant molecules with sp 3-C-F and sp 2-C-F bonds. These methods have employed both transition metal and photoredox catalysis, and the group has developed new reagents for mild and selective deoxyfluorination ...
In organic chemistry, neighbouring group participation (NGP, also known as anchimeric assistance) has been defined by the International Union of Pure and Applied Chemistry (IUPAC) as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma or pi bond contained within the parent molecule but not conjugated with the reaction centre.

Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Some Wikipedians have formed a project to provide information related to chemistry. The main efforts focus on providing articles clearly written articles that give an overview of the topic, all supported by reliable sources. The Chemistry portal is maintained at Portal:Chemistry and the project banner is {{WikiProject Chemistry}}.
In organic chemistry, a coupling reaction is a type of reaction in which two reactant molecules are bonded together. Such reactions often require the aid of a metal catalyst.
The Messenger Lectures are a series of talks given by scholars and public figures at Cornell University.They were funded in 1924 by a gift from Hiram Messenger of "a fund to provide a course of lectures on the Evolution of Civilization for the special purpose of raising the moral standard of our political, business, and social life", to be "delivered by the ablest non-resident lecturer or ...
